I saw two videos of people not paying attention to their surroundings and got their gun snatched out they pocket. be aware of your surrounding if you are open or partially visually carrying.
How would someone know another person has a firearm in their pocket?
There are definitely signs if they’re not carrying very responsibly (I’ve seen people pocket carry in sweat pants - and you KNOW they have a firearm in their pocket because it is almost falling out of their pockets as their pants are near falling down.
Hense the reason I carry appendix!
